Graph the polar equation for θ in [0, 360).
Which is the correct answer?
Inspect the four given graphs, which are plotted in polar coordinates (and shown in an attached .doc file), and choose the graph that corresponds to the polar equation r = 6 - (cos theta).
Characteristics of three of the given graphs are used to eliminate them as candidates for the graph of the given equation, and a few key points of the remaining graph are checked and verified.
